Research notes
Research notes

Price is Amazon's current one-time price (sold by Amazon.com; no deal badge or Typical price shown on 2026-10-20). protein2o.com would not load, so nutrition comes from the label image on the Amazon listing (the bottle now reads 'Protein Hydration Drink with Electrolytes'). The label gives total sugars as '<1g', recorded here as 1. Carbs include 4g erythritol. Clear whey protein isolate.
